IoT powered by Microprofile
summary
A tiny over‑engineered office IoT stack that controls lamp color and brightness with a gateway, light‑control, time and weather services built on MicroProfile and run with Docker Compose, demonstrating CDI, Config, Health, Metrics endpoints (Prometheus format), the typesafe REST client, and fault‑tolerance features like retry and circuit‑breaker plus timeout/fallback. Services switch between Payara/Open Liberty/Quarkus by changing pom/config only. Vendor SDK and direct REST control both used; live demo mostly works but a Wi‑Fi outage forces onstage debugging.
